Battery mounting

A project log for Retrofit Robot

Turning one of my old favorite toys from my childhood into a raspberry pi zero based internet controlled robot.

I thought a lot about how the battery will be mounted in a secure way. I ended up cutting a piece of meccano that I found inside my old toy boxes and will be using two screws bolted to the chassis to hold the battery.



I also thought about how the robot will keep track of the current position inside a room.

Found a USB mouse that might be used to track how long the robot has travelled in each direction.



The caps needs to be desoldered and moved since the space between the battery and the bottom is quite limited.

Personally I love to use velcro tape for securing batteries. Strong enough, soft (so the battery is not damaged), and easy to replace.

I love the use of a mouse as an encoder. I suppose you will simply connect it to the USB as a normal mouse?

Velcro is good idea. I think the tape I use will work well too, it feels a bit like a soft sponge and is normally used to decrease vibrations in ventilation equipment.

I plan on connecting the mouse to one of the usb ports and then see if I can read the data from a python script. From what I have read so far, computer mice can be quite accurate as a odometer.

Hopefully it will work pretty nicely but I need to do more tests to see if it works as good in practice.
